Stocky and muscular, an adult wolverine is about the size of a medium dog, resembling a small bear with a long tail. It has glossy brown hair with stripes of dull yellow along the sides. Long, dense fur helps adapt the wolverine to its cold Northern habitat. They can give off a very strong, unpleasant odor, leading to nicknames of "skunk bear" and "nasty cat." They are the only species currently classified in the genus Gulo which means "glutton." The total world population of wolverines is unknown. They exhibit a low population density and require quite a large home range.
What they eat: Wolverines are carnivorous, eating a variety of animals their own size or smaller. Occasionally they will eat plants.
Where to find them: Isolated northern areas: arctic and alpine regions of Alaska, northern Canada, Siberia, Scandinavia, Russia and Baltic countries.
Claim to fame: Armed with powerful jaws and a thick hide, wolverines are remarkably strong for their size; they have been known to kill moose, and by one published report, a black bear.
